Hello, I don't know how to make Exchange Server to communicate to outside world. We have VPN Server and Proxy Server in our network. And both of them have two network cards one for internal network another for internet connection. Cards for internet connection are connected to the old Cisco firewall pix 501 and firewall is connected to the simple netgear router. I don't know how to connect Exchange Server to the network, because it has only one network card. I dont know if I can connect firewall straight to our network (so I would be able to forward apropriate ports to the servers) or I have to put something between firewall and internal network and pass SMTP traffic throught that device. I would be pleased to hear any suggestions. Thanks
Have the Pix port forward the necessary Exchange Ports, typically 25 and 443.

I can not forward ports to my Exchange because my firewall is connected to VPN server and Proxy Server and Exchange 2003 is sitting behind these servers on the internal network. I am not sure if it is right topology, because the guy before me done all that. I think I have to connect firewall to our internal network so only then I would be able to do port forwarding.

So the VPN and Proxy Server are sitting in a DMZ? If so, then you will need to configure one of the ports on your Pix for a secure connection to your internal network. It allows for up to 8 vlans if you have the 8 port model. The ASA 5505 allows for this but you did not state what model you have. And why do you have a separate VPN device when the Pix can provide this capabality? Why the Proxy Server? -- John Oliver, Jr MCSE, MCT, CCNA Exchange MVP 2008 Microsoft Certified Partner "Donatas Grasys" wrote in message news:fnaaf4$9fn$1$8300dec7@news.demon.co.uk... >I can not forward ports to my Exchange because my firewall is connected to >VPN server and Proxy Server and Exchange 2003 is sitting behind these >servers on the internal network. > I am not sure if it is right topology, because the guy before me done all > that.
